<h2>Parameters</h2>
<dl>
<dt><i>Server</i> [in]</dt>
<dd>
<p>Specifies the process server to use to attach to the process.  If <i>Server</i> is zero, the engine will connect to the local process without using a process server.</p>
</dd>
<dt><i>CommandLine</i> [in, optional]</dt>
<dd>
<p>Specifies the command line to execute to create the new process.  If <i>CommandLine</i> is <b>NULL</b>, no process is created and these methods will use <i>ProcessId</i> to attach to an existing process.</p>
</dd>
<dt><i>OptionsBuffer</i> [in]</dt>
<dd>
<p>Specifies the process creation options.  <i>OptionsBuffer</i> is a pointer to a <a href="#Bookmark880"><b>DEBUG_CREATE_PROCESS_OPTIONS</b></a> structure.</p>
</dd>
<dt><i>OptionsBufferSize</i> [in]</dt>
<dd>
<p>Specifies the size of the buffer <i>OptionsBuffer</i>.  This should be set to <b>sizeof(DEBUG_CREATE_PROCESS_OPTIONS)</b>.</p>
</dd>
<dt><i>InitialDirectory</i> [in, optional]</dt>
<dd>
<p>Specifies the starting directory for the process.  This parameter is used only if <i>CommandLine</i> is not <b>NULL</b>.  If <i>InitialDirectory</i> is <b>NULL</b>, the current directory for the process server is used.</p>
</dd>
<dt><i>Environment</i> [in, optional]</dt>
<dd>
<p>Specifies an environment block for the new process.  An environment block consists of a null-terminated block of null-terminated strings.  Each string is of the form:</p>
<div class="code"><span codelanguage=""><table>
<tr>
<th></th>
</tr>
<tr>
<td>
<pre>name=value</pre>
</td>
</tr>
</table></span></div>
<p>Note that the last two characters of the environment block are both <b>NULL</b>: one to terminate the string and one to terminate the block.</p>
<p>If <i>Environment</i> is set to <b>NULL</b>, the new process inherits the environment block of the process server.  If the DEBUG_CREATE_PROCESS_THROUGH_RTL flag is set in <i>OptionsBuffer</i>, then <i>Environment</i> must be <b>NULL</b>.</p>
</dd>
<dt><i>ProcessId</i> [in]</dt>
<dd>
<p>Specifies the process ID of the target process to which the debugger will attach.  If <i>ProcessID</i> is zero, the debugger will attach to the process it created from <i>CommandLine</i>.</p>
</dd>
<dt><i>AttachFlags</i> [in]</dt>
<dd>
<p>Specifies the flags that control how the debugger attaches to the target process.  For details on these flags, see <a href="#Bookmark878"><b>DEBUG_ATTACH_XXX</b></a>.</p>
</dd>
</dl>
<h2>Return value</h2>
<p>This method may also return error values.  See <a href="#Bookmark909"><b>Return Values</b></a> for more details.</p>

</table>
<p> </p>
<h2>Remarks</h2>
<p>This method is available only for live user-mode debugging.</p>
<p>If <i>CommandLine</i> is not <b>NULL</b> and <i>ProcessId</i> is not zero, then the engine will create the process in a suspended state.  The engine will resume this newly created process after it successfully connects to the process specified in <i>ProcessId</i>.</p>
<div class="alert"><b>Note</b>    The engine doesn't completely attach to the process until the <a href="#Bookmark465"><b>WaitForEvent</b></a> method has been called.  Only after the process has generated an event -- for example, the create-process event -- does it become available in the debugger session.</div>
<div> </div>
